Document Type and Number:
Japanese Patent JP3730066
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simplify manufacturing work by a method wherein a volume main body can be easily fixed to an input device at a rotation position from which a neutral point voltage is outputted.
SOLUTION: A rotation shaft 3a, a screw 3d and a part of a volume main body 3b are fitted in a boss 21b. An anchor chip 3c is fitted in an oblong hole 21c of a plate 21a, and the volume main body 3b is attached to a boss 21. A protrusion 23c is fitted in a shaft hole 11b, and a trim lever 23 is attached to a base 11. A protrusion 22c is fitted in a hole 23b, and a collar 22 is attached to the trim lever 23. The boss 21b is fitted in a hole 11a of the base 11 via a hole 22a and an oblong hole 23a. Inside the base 11, a nut 25 is screwed with the screw 3d via a washer 24. By elastically deforming an elastic chip 22b to the base 11 side, a protrusion 21d is engaged with one of recessed parts 22d, and rotation of the boss 21 and the volume main body 3b is regulated.
